Question

 When an object is free falling, I understand that the earth's gravity causes its velocity to increase at 10 meters/second2 in the downward direction. Is there a point at which this object would reach a "terminal velocity" in the earth's atmosphere an?

Answer Yes, most objects will reach a terminal velocity and stop accelerating downward. The faster an object drops, the more air resistance it experiences. This air resistance pushes the object upward and... Read More »

How to Calculate Terminal Velocity of a Falling Object?

By definition, an object hits its terminal velocity when it reaches the point in its fall when it is travelling at a constant rate. The shape and mass of the object, as well as the medium it is tra... Read More »

Is terminal velocity the same for every object of the same mass or can the terminal velocity of two parachutists (same weight and height) be different -CV?

Terminal velocity is the result of a delicate balance between two forces—an object's downward weight and the upward drag force that object experiences as it moves downward through the air. Termin... Read More »

In "Empire Strikes Back", when Luke learns that Darth Vader is his father, he falls/jumps off a platform in Cloud City without his hand. Given the fact that objects reach terminal velocity, which would have a faster terminal velocity and which would ?

Luke would probably reach the ground before his hand. An object reaches a terminal velocity as it fall because the upward force of air resistance becomes stronger as the object's downward speed inc... Read More »

What is the approximate terminal velocity for a spent falling bullet that was fired into the air Is this velocity sufficient to kill someone - M?

A bullet's terminal velocity is the downward speed at which the upward force of air resistance acting on it balances its downward weight. Once the falling bullet reaches this speed, it coasts downw... Read More »
